• 如何在我的sql中将时间序列作为小数(17,3)储存?
原标题:How to store the timestamp as decimal(17,3) in mysql?

我试图产生一个触发点,在触发声明中,我必须设置一个精度(17,3)的栏目,配备实际的时间或分数,但无法找到解决办法。

最佳回答

我找到了解决办法。

2. 具体列明了原表中的数据类型,即:精度(17,3)的清点图,与 Java型大Dec体相当,其功能简单:

public static Date bigDec2Date(BigDecimal tsp) {
    Calendar cal = Calendar.getInstance();
    cal.setTimeInMillis(tsp.longValue());
    return cal.getTime();
}

        System.err.println(decimalTime);

在我的SQL中:

SELECT timestamp( <decimalTime> );// eg:-
